ALPAQUITA array in the ALPACA project

ALPACA Collaboration

Research output: Contribution to journalConference articlepeer-review


We are now proposing a new project which consists of a large air shower array (83, 000 m2) and a muon detector array (5, 400 m2) located at the altitude of 4, 740 m near La Paz in Bolivia to observe 100 TeV gamma rays in the southern sky. The ALPAQUITA array is a prototype air shower array which will be constructed at the ALPACA site. This array consists of 45 scintillation counters of 1 m2 in area each, and its effective area is approximately 8, 000 m2 (1/10 of ALPACA air shower array). In the present paper, we report on the current status and the performance of the ALPAQUITA array.
